To all whom t may concern.'

Be it known that l, Nain lnrnonnaiv CAM- nnoN, of the 'town of Shoal Lake, in the Province of Manitoba, Canada,l have invented certain new and useful improve'- ments in Attachments for Bundle Carriers, of which the following is a specification.

The invention relates to improvements in attachments for bundle carriers .and the object of the invention is to provide an attachment on the customary form of binder bundle carrier which will positively prevent the sheaves discharged on to the bundle carrier from escaping' prematurely overthe ends of the bundle carrier teeth and will also allow of more sheaves being carried by the bundle carrier prior to discharging` them, thereby making better rows of sheaves which not only facilitates in stocking opera,- tions but also in the loading of the sheaves.

A further object is to arrange the structure of the attachment so that it can be readily applied on existing types of binders and such that the whole device can be made in a cheap, strong, durable and reliable manner and entirely automatic in its action.

With the above objects in view the in: vention consists essentially in a plurality of sheaf retainers located at the outer eX- tremities of selected teeth of the carrier and means for controlling the retainers to hold them positively against movement in the upright position during the interval that the carrier is being loaded and to drop them during the unloading movement of the carriers and to return them to their original u'lnight position when the bundle carrier is returned to receiving position, the. parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying draw ing in which -F ig. l is a perspective view of the bundle carrier fitted with'my invention.

Fig. 2 is a plan view of a portion of the bundle carrier.

Fig. 3 is an enlarged sectional View through the bundle carrier shaft.

ln the drawing like characters of refern ence indicate corresponding parts in the several figures.

l have not considered it necessary to enter into the details of the binder as the struc ture of the binder as well as the bundle BUNDLE CARRIERS.

carrier is well known. Only those parts immediately associated with my invention are described and whilst these are shown and described in detail it will be readily understood that l do not Wish to be limited to the precise construction shown as this varies in the various types of binders and my invention would be modified to comply with the existing conditions.

l and 2 are a pair of stationary end brackets extending from the side of the binder and which are utilized to support the bundle carrier shaft 3 in the ordinary position. The shaft 3 carries a plurality of similar normally horizontally extending teeth 4l: which have their outer ends slightly up-turned as indicated at 5 and their inner ends bent upwardly and passing pivotally through the shaft and then bent downwardly as indicated at G and all connected swivelly to a connection bail 7. This bar is to the rear end in a lower plane than the shaft and the arrangement is such that by end shifting the barthe outer tips of the teeth' can be all swung simultaneously rearwardly and such that upon the shaft being rotated the teeth can be thrown down towards or raised from the ground.

ln the bundle carriers as at present used and as shown these down swinging' and rearward turning actions occur simultaneously, the teeth dropping and swinging rearwardly to effect the discharge of the bundles carried by the teeth in an easy and gradual 'manner'. The shaft and the bar are controlled in their movement by the means hereinafter described.

8 is a rotatably mounted operating rod fitted with a downwardly extending crank i). the lower end of which is connected by means of a pitinan lo to the bar 7. rl`he shaft is supplied with an upwardly eX- tending crank ll which is connected by means of a link l2 also with the crank 9. Obviously the rotation of the rod 8 in a proper direction will shift the crank 9 reariardly which action will produce two movements to wit :-an end movement in the bar 7 and a rotary movement in the shaft 3 which movements are the ones which give the teeth thev back turning and down dropping movement herein before mentioned.

All the above parts are of ordinary construction and do not form any part of my invention. A bundle carrier so constructed will only hold a limited number of sheaves and it more are put on it one or more will be crowded over the ends ol`jl the teeth and be prematurely deposited or split, such causing irregular rows and giving' trouble during stooking and loading operations.

To obviate this diiiiculty l have provided the following parts as an attachment for the bundle carrier.

The outer ends or tips of a number of selected teeth are vertically slotted as shown at 13 to receive a sheai retainer 14, the retainer being in the nature of a flat bar pivotally fastened by a pivot pin 15 to the teeth so that there is a long end extending upwardly and a short end extending downwardly.

Each retainer is controlled by a controlling rod 16 slidably attached by suitable clips 17 to the underside of kthe selected teeth 4. These rods pass inwardly towards the binder and have their outer ends connected by pairs ot links 18 to the lower ends ot the retainers 14 and their inner ends terminating in headsl 19.

rllhe heads ot the rods are adapted to engage with a horizontally disposed controlling guide bar 20 permanently secured to the lower ends o1? a pair of end hangers 21 and 22 attached to the end brackets. This bar is for the greater part straight but is provided in a proper location with bowed parts 23 and 24, the curvature of which is determined by the movement ot the teeth.

In the normal outstanding position o't' the teeth the shea'f retainers 14 take an upright position as shown in the drawing, the upper ends being locked against outward swing by the heads 19 of the controlling rods being engaged with the straight part ot the bar 20.

Consequently the retainers positively prevent the sheaves 'from escaping prematurely over the ends of the teeth and being scattered on the ground and also allow or more sheaves being deposited on the carrier than is customary.

In the movement of the teeth as effected through the turning ot the rod 8 the controlling rods are caused to swing with the teeth and to follow the movement thereof with the result that when the outer ends of the bundle carrier teeth drop the inner ends of the controlling rods ride and escape from the controlling rod guide bar. The controlling rods are consequently then tree to shift endwise towards the binder and the instant they are tree the upper ends of the retainers swing out to approximately a horizontal position as it is to be remembered that the sheaves carried by the bundle carrier have a constant outward pressing action on the retainers which sets them in motion the instant the heads 19 are free.

After the heads of the controlling rods free the guide bars they continue moving with the teeth and actually swing forwardly. The movement ust described allows the retainers to unlock and drop down and free the sheaves and take approximately a horizontal position when the bundle carrier has reached its dropped rear position as shown in dotted outline Figure 2.

1n the return movement ot the bundle carrier teeth which is brought about by turning the rod 8 in the reverse direction, the initial movement is the raising of the outer ends of the teeth, which movement lowers the heads of the controlling rods into the plane ot the controlling rod guide bar. The further movement or the teeth on the return, swings the control rods in the direction indicated by the dotted line 25 (Figure 2) where they are brought to the curved part of the bar and in travelling this curved part are gradually shoved endwise outwardly with the result that when the'teeth have reached the original loading position the control rods have been pushed outwardly to their 'full extent and the retainers have been again brought to their original upright position in which they are locked against outward swing.

1 have shown the retainers as mounted on two teeth but it will be readily understood that the number could be increased as desired provided guide rods are supplied to control them.

lVhat I claim as my invention is 1. In a bundle carrier, the combination with sheaf receiving and bundle forming teeth and means for operating the teeth to discharge the bundle and return to the original sheat filling position, of shear retainers located at the outer ends of selected bundle carrier teeth and means Jfor controlling the retainers automatically operating to hold them in a fixed position in the sheaf illing position of the carrier teeth, to release them in the discharging movement of the carrier teeth and to reset them in the initial position upon the carrier teeth returning to the original sheat receiving position.

2. In a bundle carrier, the combination with sheat receiving and bundle forming teeth and means ior operating the teeth to discharge the bundle and return to the original sheaf filling position7 of a plurality ot sheai4 retainers carried by selected teeth and located at the outer ends of the teeth, means for locking the retainers in an upright position against the outward pressure ot the sheaves and means for releasing and returning the sheat retainers to comply with the discharge and return movement ot the teeth.

1n a bimdle carrier, the combination with shea'i' receiving and bundle forming teeth and means for operating the teeth to discharge the bundle and return to the origi- .nal shea't filling position7 of a plurality of normally upstanding shea'f retainers located at the outer endsvof selected teeth, en'dWise movable controlling rods carried by the teeth and connected to the retainers and a permanently mounted guide bar engageable with and controlling the movement of the rods and designed to lock the rods against end movement inwardly in the shear receiving position of the teeth and thereby prevent the outward swinging of the upper ends of the retainers and in the discharging' and resetting mofvement of the teeth t0 release the rods in the discharge movement and to reset them in the initial looked position on the return movement.

4. An arrangement according to Claim 3, in Which the permanently mounted guide bar is provided with an irregular bearing surface engageable with the endwise movable controlling rods.
